Abstract
A 50-year-old man underwent coronary angiography for stable angina with evidence of
chronic total occlusion of the right coronary artery. Chronic total occlusion recanalization
was performed with implantation of 4 overlapping bioresorbable vascular scaffolds.
At 12 months, elective follow-up coronary angiography documented an asymptomatic 90%
in-scaffold restenosis of the right coronary artery located in the mid portion of
a newly late-acquired aneurysm. To address the challenging issue introduced by the
varying reference vessel diameters, a self-expandable stent was implanted.
Résumé
Un homme de 50 ans a subi une coronarographie pour une angine stable montrant une
occlusion totale chronique de l’artère coronaire droite. La recanalisation de l’occlusion
totale chronique a été réalisée au moyen de l’implantation de 4 endoprothèses vasculaires
biorésorbables qui se chevauchent. À 12 mois, la coronarographie de suivi a démontré
une resténose intrastent de 90 % asymptomatique de l’artère coronaire droite située
dans la partie moyenne d’un anévrisme acquis récemment. Pour régler le problème complexe
que représentent les différents diamètres vasculaires de référence, une endoprothèse
auto-extensible a été implantée.
